This driver uses 'struct timeval' which we are trying to remove since 32 bit time types will break in the year 2038. So replace it with 'ktime_t'.

Replaced do_gettimeofday() with ktime_get() because ktime_get() returns a 'ktime_t' while do_gettimeofday() returns a 'struct timeval'.

This patch also uses ktime_us_delta() to get the elapsed time.

Signed-off-by: Amitoj Kaur Chawla amitoj1606@gmail.com --- Changes in v2: -Removed the build error ktime_us_delta() was giving.
